چکیده انگلیسی:
To be able to grow crops, we have interfered with Earths reserves of one of top three essential elements, phosphorus (P), as to which we face a problem related to its high consumption compared to available resources. This
forces us to follow the alternative of closing the phosphorus loop from a circular economy perspective. However,
there is a lack of research on regional and global social sustainability in this area, as emphasized in the United
Nations Agenda 2030 goals for sustainable development. In this paper, we address social challenges involved
in global phosphorus supply chain, such as eradicating poverty, child labor and malnutrition; promoting gender
equality; providing decent work and economic growth; maintaining sustainable water use; and achieving food
security. Our research is driven by the question of whether the circular economy aims to direct phosphorus
management towards tackling social issues associated with its supply chain. We use system dynamics modelling
by combining the concept of material flow analysis and social life cycle assessment. Detailed analysis at regional
and global levels indicates a paradoxical social impact of phosphorus circular model. This reflects the multiple
stakeholders involved, and the regional interactions with phosphorus circular economy transitions.
Improvements can be demonstrated in reducing poverty and providing safer work environment in many regions,
e.g., Western Asia (93%), New Zealand, Central Asia, and Europe (44–61%), while achieving employment targets
is limited in Northern and Eastern Europe. Circular model fails to promote gender equality, it also exacerbates
exploitative child work problem for the Caribbean and most Africa. It provides sufficient nutrition to North
America, Australia/New Zealand, and Northern Europe. It achieves water use targets in several regions with
53% savings worldwide. Finally, circular model contributes to P efficiency (average balance of 1.21 kgP/ha) and
strengthens P security within most regions with an average of 64%.
